GENERAL NOTES MINIMUM BEARING REQUIREMENTS 1-3/4" minimum bearing length is required at SpaceJoist TE ends. Reinforcement, or closure refers to 3/4" APA rated sheathing or other 3/4" exterior grade 48/24 span rated sheathing that is cut to match the full depth of the SpaceJoist TE. Rim boards and cantilever reinforcement must bear fully on the bearing wall. NAILING REQUIREMENTS If nailing SpaceJoist TE at bearing, use two (2) 8d nails (1 each side) placed a minimum of 1-1/2" from end of joist. Toe-nail rim board to bearing plate with 8d (box or common) at 6" O.C. per APA specifications. When used for shear transfer, nail to bearing plate as specified by the building designer. Nail rim board or closure to SpaceJoist TE with two (2) 8d nails. Attach squash blocks (2x4 minimum) per DETAIL B and DETAIL D to top chord and bottom chord with two (2) 8d nails. RESIDENTIAL FLOOR SPAN TABLES RESIDENTIAL FLOOR SPAN TABLES FOUND ON PAGE 8. Up to 12" may be field-trimmed from each end of the SpaceJoist TE truss. Contact your SpaceJoist TE representative or Engineering Department prior to any additional trimming. Span charts reflect the benefit of composite action afforded by a glued-nailed or glued-screwed connection of the sheathing to the top chord of the truss. Consult your SpaceJoist TE representative for appropriate spans if a nailed-only or screwed-only connection is to be utilized. DECKING For the best floor performance of SpaceJoist TE, use a minimum of 3/4" T&G APA rated sheathing, glued & screwed or glued & nailed in accordance with APA and local building code specifications. RIM BOARD AND BLOCKING For single-story applications and second story applications, refer to DETAIL A. For main floor rim of two-story application refer to DETAIL A. Details provide 4,400 plf vertical load transfer for each 1-1/8" rim board. Refer to page 18 for other rim board load transfer information. Details in this manual are the same as those represented on the SpaceJoist TE installation poster. Span dimensions are out-to-out at bearing supports. Minimum required bearing length is 1-3/4". Span charts are for the uniformly loaded conditions specified in the heading of each chart. For SpaceJoist TE trusses supporting concentrated (point) loads, cantilevered end conditions, or other special loading conditions, contact your TE representative. BRACING Strongback bracing, as shown in DETAIL S on page 10, is required in accordance with ANSI/TPI 1-2002, Section 7.5.2.4 and BCSI 1-03. Strongback bracing minimizes vibration and localized deflection in the floor system. WEB STIFFENER REQUIREMENTS Web stiffeners are required if the sides of the hanger do not laterally support the SpaceJoist TE top flange. Some spans may require top chord supports and/or web stiffeners. Contact SpaceJoist TE engineering for required reinforcements. Span charts for additional loadings are available from your SpaceJoist TE representative. 5
